ELECTRIC-LAMP-SOGKET ATTACHMENT.

Application led August 4, 1924. Serial No. 730,093.

This invention has relation to electric lamp sockets and refers more particularly to a substitute cap for the closed end of the socket which is provided with means thereon for associating therewith an attaching device whereby the lamp socket and lamp may be readily combined with a vase or other supporting element to produce a reading lamp without the necessity of drilling holes or otherwise cutting or fitting the same. l

One ot the outstanding objects of the present invention resides in the provision of a simple and inexpensive attachment which is designed to take the place of the ordinary cap for the closed end of an electric lamp socket and by means of which the said socket may be properly associated with a vase or other desired article to constitute a supparting base therefor.

With the above recited and other objects in view. the invention resides in the novel construction set forth in the following speciiication, particularly pointed out in the ap- 35 pended claims and illustrated in the accomof the terms in which the claims are eX- pressed.

in the drawings- Figure 1 is a side View partly in section illustrating the attachment in active use;

Fig. 2 is a ver-tical sectional view through the attachment applied to the lamp socket; and

Fig. 3 is a perspective view of the attachment removed from the socket.

Referring to the drawings by characters of reference designates an electric lamp hey socket having the usual switch mechanism 11 therein operated by the key 12 to close or open the circuit for lighting or eX- tinguishing the lamp 13 which is applied thereto. The attachment constituting the invention consists of a cylindrical cap member 15 having a closed end 16 and an open end 17 the latter being of slightly greater diamfr" eter than the former and having diametrically disposed notches or cutaway portions 18 to accommodate the dialnetrically projecting extremities of the switch key 12. The outer periphery of the medial portion of the screw threads 19 which are designed to receive the threaded bore or sleeve portion 20 of a standard lamp shade holder 21 which shade holder is provided with thek usual clamping screws 22 threaded radially therethrough. Under this arrangement the substitute cap member 15 when in applied relation to the socket member 10 with the standard shade holder 21 threaded thereon may be supported from the upper end of a vase 28 which is designed to constitute the base for'supporting the lamp and socket. Adjacent the opposite open end the socket member 10 is provided with the standard external screw threads 24 with which the ordinary shade holder is associated for supporting the lamp shade 26.

From the foregoing it will thus be seen that an extremely simple and inexpensive attachment has been provided by means of which an ordinary lamp socket may be attached to a suitable supporting base to provide a lamp, for the home, work shop7 garage or any other use to which it may be adapted.

I claim:

1. As a new article of manufacture, a substitute cap for the closed end of a shell of an electric lamp socket having a notch in its inner edge affording means to permit of the leading in of the conductor wire between said substitute cap and the socket shell, and means formed on said cap to facilitate the association therewith of a device for establishmg a connection between the substitute cap and a vase or other similar article to he used as a supporting base. l

2. As a new article of manufacture, a substitute cap for telescopically engaging` over the closed end of the shell of an electric lamp socket, said substitute cap having a notch at its inner end to permit of the leading in of the conductor wire between the substitute cap and the socket shell, and means provided on said cap for engagement with a device for associating the same with a vase or other similar article to be used as a supporting base for the socket, the said means consisting of a threaded portion on said substitute cap, and a clamping member for the end of the base vhaving a complementary threaded portion.

3. The combination with an electric lamp socket and a vase or other similar article to be used as a supporting base for the socket to provide a lamp, of a substitute cap adapt ed to be arranged over the closed end of lift the socket, said cap having an exteriorly threaded portion with a notch in the end Which fits over the socket, whereby a clamping element having- 'a Complementary 5 threaded portion adapted to receive the threaded portion of the'Substitute cap may be associated with the socket for clamping.

the notched portion of the substitute cap eonstitutinggmeans for leading the conductor Wires from the soeketexteriorly of the snp'porting hase.
